  In order to evaluate the chill forming tendency of molten spheroidal graphite cast iron, critical cooling rates for chill formation have been determined by measuring cooling curve and the corresponding chill area (area of eutectic cementite) of several samples with different chiller thickness. It is difficult to accurately measure the cooling rate of liquid during solidification using ordinary thermocouples because of poor response. When maximum cooling rate after solidification is used in place of cooling rate during solidification, a good relationship between the maximum cooling rate and chill area is obtained. With this method, the chill forming tendency of certain kinds of molten spheroidal graphite cast iron can be evaluated based on their different chill forming tendencies.
